System Description: Notes
WARNING: This page is about a different car, the 2005 Infiniti FX45 and 2005 Infiniti FX35. However, it is still accessible from the selected car via links, so may be relevant.
Daytime light system turns ON daytime light lamps while driving. Daytime light lamps are not turned ON if engine is activated with parking brake ON. Take off parking brake to turn ON daytime light lamps. The lamps turn OFF when the lighting switch is in the 2ND position or AUTO position (headlamp is ON) and when the lighting switch is in the PASSING position (daytime light lamps are not turned OFF only by parking brake itself).
The parking brake signal and engine run/stop signal are sent to BCM (body control module) by CAN communication line, and control daytime light system.
